Abstract
A miniature device comprising a substrate and primary and secondary movable members overlying the substrate. First and second suspension members couple the secondary movable member to the substrate. Third and fourth suspension members couple the primary movable member to the secondary movable member. A lever assembly is provided and has a pivot and a lever coupled to and pivotable about the pivot. The lever has a first extremity coupled to the primary movable member and an opposite second extremity. The secondary movable member is coupled to the lever between the first extremity and the pivot.

A miniature device comprising a substrate, primary and secondary movable members overlying the substrate, first and second suspension members for coupling the secondary movable member to the substrate, third and fourth suspension members for coupling the primary movable member to the secondary movable member, a lever assembly having a pivot and a lever coupled to and pivotable about the pivot, the lever having a first extremity coupled to the primary movable member and an opposite second extremity, and a coupler for coupling the secondary movable member to the lever between the first extremity and the pivot.
A miniature device comprising a substrate, a translatable element and an intermediate element overlying the substrate, at least one folded flexural suspension having a first flexural element for coupling the intermediate element to the substrate and a second flexural element for coupling the translatable element to the intermediate element, a pivoting lever having an extremity, a first coupler for connecting the translatable element to the extremity and a second coupler for connecting the intermediate element to the lever so as to constrain the intermediate element to translate substantially half the translation of the translatable element.
A miniature device comprising a substrate, a primary movable member overlying the substrate and having first and second spaced-apart portions, a secondary movable member overlying the substrate and having first and second spaced-apart portions, first and second suspension members, the first suspension member having a first end portion coupled to the substrate in the vicinity of the first portion of the primary movable member and a second end portion coupled to the first portion of the secondary movable member and the second suspension members having a first end portion coupled to the substrate in the vicinity of the second portion of the primary movable member and a second end portion coupled to the second portion of the secondary movable member, third and fourth suspension members, the third suspension member having a first end portion coupled to the first portion of the secondary movable member and a second end portion coupled to the first portion of the primary movable member and the fourth suspension members having a first end portion coupled to the second portion of the secondary movable member and a second end portion coupled to the second portion of the primary movable member, a lever assembly having a pivot and a lever coupled to and pivotable about the pivot between first and second positions, the lever having a first extremity coupled to the first portion of the primary movable member and an opposite second extremity, and a coupler for coupling the secondary movable member to the lever between the first extremity and the pivot, the movement of the lever from the first position to the second position causing the first extremity of the lever to move the primary movable member in a substantially linear first direction of travel a first distance and causing the coupler to move the secondary movable member in a substantially linear second direction of travel a second distance that is half as long as the first distance.
